To all whom it may concern:

Be it known that I, ANTHONY P. HINSKY, a citizen of the United States,and residing at Hoboken, in the county of Hudson and state of NewJersey, have invented certain new and useful'lmprovements in Machinesfor Making Tubular Electric-Wire Conduits, of which the following is aspecification, such as will enable those skilled'in the art to which itappertains to make and use the same. V

This invention relates to machines for making tubular electric wireconduits, and the object thereof is to provide an improved machine forthis purpose by means of which tubular electric wire conduits may bemade from a strip of paper board, or thick heavy cardboard and providedwith a fabric covering, the tubular conduit consisting of a core orinner-member formed from a strip oi paper or other fibrous material andcoated or covered with preservative and insulating solution and a fabriccoating or covering applied thereto and 315,011

saturated and covered or coated with a preservative and insulatingsolution.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in'wln'ch the separateparts of my improve:

ment are designated by suitable reference characters in each of theviews, and in which;- 4

Figure 1 is a sectional side view of my improved machine for makingtubular electric wire conduits; Fig.

2 a partial section on the line 2-2 of Fig. 1; Fig. 3 a

- partial section on the line 3-3 of Fig. 1; Fig. 4 a partial section onthe line 4-40iFig. 1; Fig. 5 a side view showing details ofconstruction, Figs. 2, 3, 4 and 5 being on a scale larger than that ofFig. 1, and 6 a transverse section of one of a pair of feed wheels orrollers which Iemploy.

In the practice ofrny invention,

\ braiding machine of this class manufactured by the N. E. Butt Companyof Providence, Rhode Islandpart of which is shown in Fig. 1. I Thebraiding machine only part of which is shown in Fig. 1 involvesasuitable frame provided with a table a on which is placed spools I)provided with threads b and machinesof this class have longbeen used forbraiding and covering tubular electric conduits, and only a partial viewthereof is given in Fig; 1 in order to show the application of myimprovement thereto. a r

1n the practice of my invention, the spool table a is provided centrallywith an aperture c, above which is placed a tubular guide c the top ofwhich is preferably tapered, and over which the frame of the machine isprovided with a transverse support a? on which is placed a tank d thebottom of which is provided with an aperture (1 and the support a isprovided with a corresponding aperture, and said tank is providedcentrally and in line with the aperture c in the table a and theaperture d in the bottom of said tank with a verti- I take an ordinarycally arranged tubular guide d The frame of the machine is also'providedover the tank d with a transverse supports, and said support is providedwith two upright bearings a in which is mounted a shaft 2 provided witha beveled gear e which meshes with a corresponding gear e on avertically arranged shaft e which is geared in connection at 'c with adrive shaft 0 provided with a pulley e. The shaft e is the drive shaftof the braiding machine but the detail construction of the braidingmachine and the connection of the shaft 0 therewith is not shown, as itforms no part of thisinvention and the construction thereof being wellknown.

' At the top of the machine frame is another transverse support a,centrally, of which is supported a depending hopper f which forms aguide for the strip 9 of paper which is formed-into a roll or wound on aroller g", and the hopper guide f is provided at its lower end with atubular sleeve f and supported vertically of the niachine and centrallythereof and passing down through the hopper guide f 2 and through thetubular guide d is a rod or mandrel h which terminates just below thehorizontal support a and just above the guide wheel '11 supported in thebottom portion of the framework of the machine, the relative position ofthe lower end of the rod or mandrel h and the wheel 71 being indicatedin Fig. 5.

The support a in the top portion of the main frame of the machine isprovided with supplemental hearings or supports a inwhich are mountedshort shafts k provided with grooved wheels or rollers'j' and thegrooves in the said'wheels are provided with teeth 7' as clearly shownin Fig. 6 and as indicated in Fig. 3, and the shafts k are provided withbeveled gears k which mesh with corresponding gears k onthe shaft e.

In practice, the tank d is filled or partially filled with. a solution mwhich is intended as a preservative coating for the paper or fibrouscore of the tubular conduit, and which also serves as an insulation forsaid core, and it i d, and one of which is shown in section in Fig. 6;and in this last operation the said tube-is grooved annularly by theteeth of :the wheels or mum; so as to formannular or circularly arrangedribs or projections and corresponding annular or circularlyarrangedgrooves in said tube as indicated at g .in Figs. 3'and 5, and thisrenders the -tubular conduit when finished more flexible than ordinarydevices of this class as usually constructed. The

tube 9 formed from the paper strip 9 after it leaves the applied, andafter the tubular conduit is provided with a fabric covering it passeson down around the guide wheel 1', and is drawn out in the direction ofthe arrow tr,

and may be rewound on a drum or on any other suitable device, and mayalso be given its last coating or covering of preservative andinsulating material in the usual or ordinary manner.

In Fig. 5 of the drawing, I have shown diagrammatically the rod ormandrel h, the paper tube 9 thereon, said tube 9 being partially coveredwith fabric as shown at g, and-I have also indicated in Fig. 5 at g apart of the covering of insulating and preservative material which thetube 9 is given before it receives its fabric coating or covering.

It will be observed that the tubular guide d does not extend to thebottom of the tubular tank d but passes .through the liquid preservativeand insulating material at this point and the coating of said materialis applied thereto during this time and the aperture d in the bottom ofthe tank 0! is 01 such size only as to permit of the requisite amount ofliquid materialin the tank d to adhere to the paper tube 9 and in Fig. 5of the drawing. the thickness of the insulating and preservativematerial g is exaggerated.

The tubular conduit or construction of which is herein shown anddescribed, is not claimed in this applicatioii but is made the subjectof a separate application executed and filed by me of equal dateherewith. It will be understood, of course, that the tubular conduitafter it leaves the guide wheel 11 may be connected with the drum orroller on which it may be wound, and the coating of preservative andinsulating material given Having fully described my invention, what Iclaim as new and desire to secure by Letters Patent, is:-

1.,.\ braiding or weaving machine provided with a con i'l'zll guide tubeover the top of which the braiding or weavinr: hikes place. a. tankplaced over said guide tube and pro hopper between said rollers, throughthe sleeve in said tank, through the aperture in the bottom-of said tankand through said guide tube.

d 2. r\ braiding or weaving machine provided with a central guide tubeover the top of which the braiding or weaving 'takes place, atank placedover said g'uide tube and provided with acentral vertically arrangedguide sleeve which does not extend to the bottom thereof, said tankbeing also provided in the bottom thereof with an aperture, :1 pair ofgrooved guide and feeding rollers mounted over said tank,

.a guide hopper mounted over said rollers, and a rod or mandrel passingvertically down through said guide hopper between said rollers, throughthe sleeve ,in said tank,

the thread spools thereof with a vertically arranged tuhular guide abovewhich the braiding or'weaving takes place, another tubular guidearranged over the first named tubular guide, a rod or mandrel passingdownwardly through both of said tubular guides, and'nicans for feeding astrip of paper downwardly through the last named tube or guide by whichit is formed into atube aroundsaid rod or mandrel and for feeding saidtube downwardly through the first named tubular guide, means for coatingsaid tube with a preservative and insulating compound ,before it reachesthe first named tubular guide; the feeding means being also providedwith means whereby the said tube is corrugated and grooved annularly. i

4. A braiding or weaving machine of the class described providedcentrally of the thread spools with a tubular guide above which thebraidingor weaving takes place. a tank supper-ted over said tubularguide and over the point where the braiding takes place and adapted tocontain insulating and preservative material, and means above said tankfor forming a strip of flexible material into a'tube and feeding itdownwardly through saidtank and through ii downwardly through said tankand through said tubular" guide and for corrugating' said tubeannularly.

In testimony that I claim the foregoing as my invention l have signed mynamo'in presence of the subscribing witnesses this 210th day of November1906.
